Can a canned peach bottle hold hot water

Yellow peach canned bottles are generally not recommended to be filled with hot water as it may pose a safety hazard. Canhead bottles are mostly made of ordinary glass material, which can easily burst when cooled or heated suddenly. In addition, the coating inside the metal bottle cap may release harmful substances when exposed to high temperatures.

Commercial yellow peach canning bottles are usually made of sodium calcium glass, which has poor heat resistance and is prone to breakage when filled with hot water due to a large temperature difference between the inside and outside. Impurities or tiny cracks in glass will accelerate their diffusion when heated, further reducing safety. The sealing gasket on the inside of the metal bottle cap is mostly made of PVC material, which may precipitate plasticizers and other components when the temperature exceeds 60 degrees Celsius. Repeated high temperature use can also cause deformation of the bottle mouth threads, affecting the sealing performance.

A very small number of heat-resistant glass material can bottles will be labeled with a temperature range, but such products are relatively rare in the market. Even when using heat-resistant glass bottles, there is still a risk of high-temperature deformation for metal bottle caps. In industrial production, canning bottles need to undergo professional annealing processes to eliminate internal stress, and the same process conditions cannot be guaranteed for daily reuse.

It is recommended to choose specialized glass containers that clearly indicate the heat-resistant temperature to hold hot water and avoid using food packaging bottles for high-temperature operations. If it is necessary to temporarily use canned bottled warm water, it should be ensured that the water temperature does not exceed 50 degrees Celsius, and sudden pouring of boiling water or direct heating should be avoided. In daily life, it can be transformed into storage jars, pen holders, and other non high temperature uses, which is both environmentally friendly and safe.
